The always get away with lying is a super power. If you say you are the President, people would believe you. You could find some evil rich guy and say "Transfer all your money to my account or the world will explode tomorrow. "

you can easily train your self to be extremely good at lying by making yourself believe what your saying is true however detecting lies is way harder extremely with extremely good liers this way i will know if your full of lies

I go to school and this boy in my class lies ALL DAY so I want to know if he's lying because he says he has money but then a few weeks later him and my friends bet if he was coming to the party and he said he had 3,000 dollars but then my OTHER friends said to bet about 50 or 100 dollars and he was like "I can't pay that!" so I want to know if someone is lying

Figuring out if someone is lying isn't hard, but to always get away with lying implies I can say anything and the listener will believe me, which means i'm then the arbiter of the world after a single broadcast. Just sayin'

You can teach yourself how to detect lies, always getting away with lying means everything, Get pulled over for a speeding ticket? "I'm sorry officer i didn't know." Boom no ticket. Rob a bank? "Someone else made me do it." Get out of jail free card.
